It is with great pleasure that we are announcing that XML Processing Model Working Group meetings have started as of last Thursday. The working group consists of about a dozen of individuals all convinced that a standard XML processing language is a necessary building stone in the XML world, and at Orbeon we are looking forward to making our best to help make that happen.
While the deliverable of the working group will certainly not be exactly XPL, we do hope that in its first version it will cover a significant number of use cases currently covered by the XPL implementation found in Orbeon PresentationServer.
XPL has been used by many OXF and OPS users over the last three years, and we believe that XPL may be the XML processing language (A/K/A XML pipeline language) that has in fact been used the most. We therefore call for users of XPL to submit their use cases: what are they, have they or do they plan to use XPL for. Feel free to submit such use cases to the ops-users mailing-list, or directly to the public XML Processing Model at
public-xml-processing-model-wg at w3.org.
